LUBRIGATORL Specification of Letters Patent.

Patented June 30, 1914.

Application filed June 7, 1913. Serial No. 772,230.

To all whom it may concern Be it known that I, EDGAR W. BAssicK, a citizen of the United States, residing in the city of Bridgeport, county of Fairfield, State of Connecticut, have invented certain new and useful Improvements in Lubricators; and I do declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the subject of lubrication, and has specially in view an improvement in lubrica'tors by means of which an absolutely dust-proof lubricator is produced, yet which is so constructed that the supplying of lubricating material to the same is facilitated.

With the above and many other objects in view, the invention contemplates the production of a lubricator of the slidable clo' sure type requiring few parts in its construction, such parts being of a nature that they mutually cooperate to normally preserve the lubricator dust-proof, and include a movable part or closure that can be actuated manually to open the lubricator for supplying lubricating material thereto, the movable part being adapted to automatically return to its closed position to seal the lubricator.

Obviously a lubricator capable of performing the functions generally stated above is necessarily susceptible to changes inde' tails and structin'al arrangements, a few practical embodiments of which are illus trated in the accompanying drawings, wherein- Figure 1 is a central vertical sectional View of the improved lubricator. Fig. 2 is a view in elevation of the stem of the lubricator. Fig. 3 is a similar view of the slidable closure. Fig. 41 is a transverse sectional'view throughthe lower portion of the stem. Fig. 5 is a fragmentary vertical sec tional view of the closure and partitions. Fig. 6 is a view similar to Fig. 1, but showing a variation of the invention. Fig. 7 is a top plan view of the stem, showing a further variation of the invention.

Referring to the accompanying drawings by numerals, it will be seen that the improved lubricator comprises in its general organization a hollow tubular stem 1, the lower end of which is externally threaded as indicated at 2, to facilitate the engagement of the stem with a bearing, journal, or the like. The upper end of the stem may be closed by aplug 3, as suggested in Fig. 1, thcplug being provided with a notch for thereception of a screw-driver or like tool for adjusting the plug, and also to attach the stem to the part to be lubricated. At intermediate points, the stem 1 is provided with one or more openings 4; which are in alinement, and said openings may, as sug gcsted in Fig. 2,be provided with locking notches (3, for a purpose to be explained.

A closure sleeve slidably surrounds the upper portion of stem 1 and normally seals the openings 4i. The sleeve 7 as suggested in Figs. 1 and 3, may have an external ring 8 formed thereon that is milled or otherwise roughened to form a finger-grip that facilitates raising of the sleeve relative to the stem. At, or adjacent, its lower end, sleeve 7 may have an out\\"ardly projecting lug 9 formed thereon to be engaged by the nozzle of an oil can to raise said sleeve. The lower edge of the sleeve provided with finger extensions, as shown in Fig. 3, which are inturned and form flat supportingledges 10 that project through the openings -11: and, by engaging the upper and lower edges of said openings, limit the longitudinal movements of said sleeve relative to the stem. The ledges 1O terminate short of the center of the stem 1, as shown in Figs. 1 and 5, leaving a central opening through which the partitions 11 depend. The partitions 11 are longitudinally concaved and have rightangularly projecting flanges 12 at their upper ends that hook over and lie flat on the ledges 10. A spring 13 is seated on the flanges 12 and bears upon plug 3, said spring serving to normally hold the flanges 12 seated upon the ledges 1.0. The plug 3 obviously holds the spring 13 under tension, and by adjustingthe said plug the tension of said spring may be regulated.

In the form of the invention described, it will be clear that the sleeve '7 can be raised whether by means of the finger-grip S or by the lug 9, to uncover the openings 4, and as the partitions are raised with the sleeve, they form independent passages for the lubricant from each opening, thereby preventing communication between the openings such as would permit the lubricant to pass transversely through the stem. As aforesaid, the sleeve 7 is raised when lubricating material is to be supplied to the stem, and when extensive lubricating is to be performed, it is desirable to hold the sleeve elevated. In such instance, a rotary movement of the sleeve will cause the ledges 10 to enter the notches 5, and thereby hold the sleeve elevated against the pressure of spring 13.

In the form of the invention shown in Fig. 1, two openings 4. are provided in the sleeve 1 and therefore two partitions 11 only are necessary. When more openings are employed, a corresponding number of partitions are employed. F or example, in Fig. 4, three partitions are shown, these obviously being used with three openings. In Fig. 1, the partitions are shown as loosely seated on the ledges 10. A variation thereof is suggested in Fig. 5 wherein the partitions are soldered or otherwise permanently fasten-ed to the ledges 10. In this form of the invention, the end flanges are short, and the spring 13 seated on the ledges 10.

A further variation of the invention is suggested in Fig. 6 wherein the sleeve 7 has its top portion provided with inwardly projecting fiat ledges S that extend through the openings 4 of stem. 1, and the bases of said openings have inwardly projecting ledges P. 'lhe free ends of ledges 8 and d terminate short of the center of stem 1, thereby providing central openings for the passage of lubricating material in addition to the spaces between the ledges. The spring 13 in this form of the invention seats on ledges 4 and bears against ledges 8 with sufficient pressure to normally retain sleeve 7 elevated so that the openings d are sealed. The upper external surface of the sleeve 7 is provided with a. ring 9 which may be milled or otherwise roughened and forms a grip for the hands of the operator, or a surface that may be engaged by the nozzle of an oil can to depress the sleeve and thereby uncover the openings 4. In this form of the invention the upper end of the stem 1 is closed by the integral cover 3* which may be notched for the reception of a screw driver and which may also be formed into substantially nut-shape to permit the stem to be grasped by a wrench.

What I claim as my invention is 1. A lubricator comprising a hollow stem provided with lubricant-admitting openings, a sleeve slidably surrounding the stem and having ledges that project through said openings, partitions depending from the ledges and adapted to prevent communication between said openings, and means for normally retaining the sleeve in position to seal said openings.
